The 75-ohm PE4314 joins Peregrine's 50-ohm glitch-less DSAs — the PE43711, the PE43712 and the PE43713 — in offering glitch-less attenuation state transitions.
When switching attenuation states with a DSA, there is a brief "glitch" or transient spike in output power. This glitch, if left alone, could
lead to degraded signal quality and possible damage to power amplifier sub-assemblies. To minimize this glitch, engineers deploy a software
or firmware workaround that reduces the effect of this transient spike. With a Peregrine glitch-less DSA, this output power glitch is significantly
reduced to less than 0.5 dB, enabling customers to decrease their engineering overhead and prevent damage to expensive sub-assemblies.

"As the founders of RF SOI, Peregrine is recognized as a performance leader in RF products," says Kinana Hussain, director
of marketing at Peregrine Semiconductor. "Our products offer best-in-class performance and proven quality and reliability. The PE4314 is a testament
to staying true to this philosophy. Peregrine introduced the world's first single-chip DSA in 2004, and we are now expanding our DSA portfolio
to include this 75-ohm solution to solve one of our customers' biggest challenges—attenuation state transition glitches."

Features, Packaging, Pricing & Availability

Supporting a frequency range from 1 MHz to 2.5 GHz, the PE4314 is a 75-ohm, 6-bit RF DSA. It is a pin-for-pin compatible upgraded version
of the PE4304, PE4307, PE4308 and PE43404 DSAs. The PE4314 covers a 31.5 dB attenuation range in a 0.5 dB step. It is capable of maintaining
0.5 dB monotonicity through 2.5 GHz. An integrated digital control interface supports both serial and parallel programming of the attenuation,
including the capability to program an initial attenuation state at power up. The DSA supports 1.8V control voltage and has an extended operating
temperature range up to 105-degrees Celsius.

The PE4314 is offered in a 20-lead 4 x 4 x 0.85 mm QFN package. Samples and evaluation kits are available now; volume production units will
be available in March.
